Why do I have to be so envious of my fellow college peers?

It’s always the same thing at college for me. We are given a lot of work. Its doable, but its a bit overwelming for me. I can never seem to get my head straight about it all. But when I look at my other student peers, they never seem to be as worried as I am. Always talking and getting along, and I peek at their homework and its either almost or completely done. I am always envious over them. I can’t even bring myself to talk to anyone in class because I just always have this inferior feeling towards them all. Like I don’t belong here sitting among them. I just started college 6 weeks ago. But ever since then I have been alone… I don’t know what to do anymore.
